Building Instructions

The four blue pegs at the end of the legs peg into
the base, and the peg at the bottom of the motor assembly must also peg
into the cross bar in the base.

15

Use a medium or long wire to connect the motor to port A on the NXT.

16

These two parts are used to cut out and attach the paper
circles. They are not attached anywhere.

Spin
Art Programming

Use the program Spin A for the Spin Art machine.
This program is called "Spin A" because it spins the motor connected to
port A on the NXT. The program also allows you to control the
speed of the motor with the buttons on the NXT brick. This program
could be used for any creation you make that needs one motor turning,
with the ability to control the motor speed.

Using the Spin Art
Machine

To make spin
art, you will need to cut out circular pieces of paper. The
separate 11-hole beam with the blue peg at the end can be used to help
you mark out circles for cutting, and the gear with the rubber pieces on
it is used to attach them to the spinning machine. See the
Instructions for Using the Spin Art Machine for
details.

Important: Make sure
both sides of the paper you use are clean and not printed or written on
in any way. Do not turn over your circles and use the bottom side
after drawing on the top. Any ink on the bottom side of the paper
circles will rub off onto the white LEGO beams of the Spin Art machine.
This includes paper already printed on one side with laser printer or
copy machine toner or ink jet printer ink.

Challenges

Try making some designs
that seem to "move" when the disk is turning, such as spirals.
Although the lowest power settings may not have enough power to turn
the paper when a pen is touching it, you can use low speeds to view
your designs that you made at a higher speed.

Try drawing or printing
some patterns on paper ahead of time and then spinning them to see
what they look like. Some patterns can create some interesting
optical illusions. Use the internet or books to find some
ideas for spinning optical illusions. For example,
here
is an example of a pattern of black and white areas that looks like
colors when spun!
